A Proxy/Client server system delivers updates. The first server you install is set as your Default Subscription Proxy server, which contacts the CA Subscription Server periodically to check for updates. Subsequent installations are configured as clients of that proxy server, contacting it for updates.
The default system reduces network traffic by eliminating the need for each server to contact the CA Subscription Server directly, but is fully configurable. You can add proxy servers as needed.
You can also reduce Internet traffic still further by creating offline proxy servers, which store update information locally and provide it to clients when contacted. Support any offline proxy servers by manually copying everything in the download path of the online proxy to the download path of the offline proxy. Offline proxies must be configured in environments where there are CA Enterprise Log Manager servers that cannot access the Internet or an Internet-connected server.
When configuring the subscription service, consider the following information about certain settings and their interactions:
Defines the default proxy server for the subscription service. The default subscription proxy must have Internet access. If no other subscription proxies are defined, this server gets subscription updates from the CA Subscription server, downloads binary updates to all clients, and distributes content updates. If other proxies are defined, clients contact this server for updates when no subscription proxy list is configured or when the configured list is exhausted. The default value is the first server installed in your environment. This value is only available as a global setting.
Controls whether the local server is a subscription proxy. An online subscription proxy uses its Internet access to get subscription updates from the CA Subscription server. Online subscription proxies can be configured to download binary updates to clients and to push content updates to the management server. An online proxy can also be used as the source for copying updates to offline subscription proxies. If selected, the Offline Subscription Proxy check box must be cleared. This value is only available as a local setting.
Note: If both subscription proxy check boxes are cleared, the server is a subscription client.
Controls whether the local server is an offline subscription proxy. An offline subscription proxy is a server that gets subscription updates through a manual directory copy (using scp) from an online subscription proxy. You can configure offline subscription proxies to download binary updates to clients. Offline subscription proxies do not need Internet access. If selected, the Subscription Proxy check box must be cleared. This value is only available as a local setting.
Note: If both subscription proxy checkboxes are cleared, the server is a subscription client.
Valid only when Update Frequency is 24 or greater.
Sets the time to begin the first update check, in whole hours, based on the local time of the server. The value is a 24-hour clock. This value applies to the initial update check. The Update Frequency controls the timing of all subsequent update checks. This setting only applies to the subscription proxy service.
Limits: 0-23, where 0 means midnight and 23 means 11:00 p.m.
Defines the frequency, in hours with which the online proxy contacts the CA Subscription server and the frequency with which the subscription client contacts the proxy. This setting only applies to the subscription proxy service.
Examples: .5 means every 30 minutes; 48 means every other day
Click this button to start an on demand update cycle immediately for the selected server. You can perform an on demand update for only one server at a time. Update the subscription proxy server before you update a subscription client.
Defines the URL of the CA Subscription server. Online subscription proxies use this URL to access the CA Subscription server and download subscription updates. This value is only available as a global setting.
Controls whether this server contacts the CA Subscription Server through an HTTP Proxy for updates, rather than directly.
Specifies the full IP Address of the HTTP Proxy.
Specifies the Port number used to contact the HTTP Proxy.
Specifies the user ID used to contact the HTTP Proxy.
Specifies the password used to contact the HTTP Proxy.
Defines the key used to test and verify the signature used to sign the updates. Never manually update this value. When a public-private key pair is updated, the proxy downloads the update to the public key value, and the proxy updates the public key. This value is only available as a global setting.
Controls how many days the proxy server retains update packages. This value is only available as a global setting.
Controls whether CA Enterprise Log Manager automatically restarts after an OS update. This value is only available as a global setting.
Lets you select which modules apply to your operating environment. Modules selected for proxies determine the modules downloaded from the CA Subscription Server as part of the subscription updates. Modules selected for clients are used to update corresponding modules installed on the client. You can select a module to download for a client that is not selected for its proxy. The proxy retrieves it for the client, but does not install it on itself.
Note: If not populated, set the RSS Feed URL. This setting lets the system read the RSS Feed and, at the next update interval, display the list of available modules to download.
Lets you set which proxies are contacted for product and operating system updates by all clients or the selected client. You can use the up/down arrows to control the order in which the client contacts the subscription proxies. The client downloads updates from the first proxy it successfully reaches. If none of the configured proxies are available, the client contacts the default subscription proxy.
Lets you select which proxies are used to distribute content updates to the user store. You can select offline proxies or online proxies. This value is only available as a global setting.
Note: We recommend that you select more than one for redundancy.
